 On the bark of trees: sparingly seen.

On the bark of trees : sparingly seen. 



N.B. ^^ Lecidea fuscoricbescens^ Nyh Port Natal, p. 8, is to be 

 separated from the present species on account of its larger and j 



more turgid spores (0-011-0'017 millim. long, O'OOT-OOIO millim. 

 thick), and to be called Lecidea Natalensis^ JSTyl." — Nyh in Vitt. 



[L. ETTPORizA, Btrn.^ sp. n.] 



On the specimen returned there is nothing rightly developed, 

 and nothing at all lecideine. It seems rather to be something of 

 a mycological nature. 



18. L. SEMiTTSTA, &tvn.^ sp. n. 

 On rocks : very fragmentary, 

 (This belongs to the section of i. tracTiona, Plot., and, indeed, 



maybe merely a state of that species ; but the fragment, on which 

 only two apothecia are visible, is scarcely determinable. Spores 

 0-009-0-011 millim. long, 0003 millim. thick.) • 



19. L. RETERTENs, Stru.^ sp. n. 

 On calcareous rocks : a mere fragment. 

 (This species is apparently closely allied to L. misella. Spores 



0-006-0008 millim. long, 0-002-0-003 millim. thick.)

 ex Strn. in Sched.]. 



On the bark of trees, associated with Periusaria pusfulata. 



(Nylander observes in Utt. that, notwithstanding the character 

 of the spores, this species is rather a Lecidea than a Lecanora, 

 Spores 0012-0-018 millim. long, 0-005-0-008 millim. thick.)
